When is he leaving the club?

Arsenal announced that Gazidis would be leaving the club for AC Milan on Tuesday, September 18.

His resignation will take effect on Wednesday, October 31.

In a statement to fans on the official website, Gazidis said: "For the last 10 years I have been privileged to dedicate myself to this great club.

"Arsenal is entering a new chapter and I have done everything I can to ensure that it is strongly placed to take on that challenge.

"This includes world-class facilities and outstanding leaders in every sector who carry the values of the club, including, of course, Unai Emery, Raul Sanllehi and Vinai Venkatesham in whom I have enormous faith.

"We have rebuilt the off-field capability of the club, which is necessary for prolonged success in modern football, we have recently concluded new primary partnership deals that, together with the new league broadcast deals, secure our medium term financial future, we have updated our stadium and rebuilt our training facilities so that they are now world class and we have transitioned to a new football structure that is capable of taking the club confidently into the future.

"I am proud to say we have done this while building on the club’s progressive social values, leading the way on the women’s game as well as diversity and inclusion."
